The Jersey Royal is the marketing name of a type of potato grown in Jersey which has a Protected Designation of Origin. The potatoes are of the variety known as International Kidney and are typically grown as a new potato.^[1]

In around 1878 a Jersey farmer, Hugh de la Haye, showed friends a large potato that he had bought. It had 15 'eyes': points from which new plants sprout. They cut this potato into pieces, which they planted in a côtil (a steeply sloping field) above the Bellozanne valley. One plant produced kidney-shaped potatoes, with a paper-thin skin, which they called the Jersey Royal Fluke. This was later shortened to 'Jersey Royal'.^[2]

In modern times, the Jersey Royal is Jersey's biggest crop export, accounting for around 70% of agricultural turnover.^[3] Ninety-nine percent of production is exported to the United Kingdom.

In 2012, 28,600 tonnes of the potato, worth £28.6m, were exported from the island. This figure was down from 30,890 tonnes in 2011.^[4]

Under the Common Agricultural Policy of the European Union Jersey Royals are covered by a Protected Designation of Origin (PDO).^[5][6]
